Mark Kelly — a retired astronaut turned gun control advocate after his wife, former Arizona congresswoman Gabrielle Giffords, was nearly killed in a 2011 mass shooting — will deliver the keynote address at the National Association of Realtors’ annual conference in November.

Kelly will take the stage on Saturday, Nov. 8, on the second day of the 2014 Realtors Conference & Expo in New Orleans, which will run Nov. 7-10. Giffords will also make a special appearance, NAR said in a press release.

Two years after Giffords was shot in the head in a shooting that killed six people, she and Kelly founded a nonprofit political action committee, Americans for Responsible Solutions, that pushes for legislation to prevent gun violence and protect responsible gun ownership.

According to the Center for Responsive Politics’ website, opensecrets.org, the Americans for Responsible Solutions “super PAC” has raised $15 million in the 2014 election cycle, but made no contributions to candidates for federal office or independent expenditures.

Asked why NAR had chosen a gun control advocate as a speaker, NAR spokeswoman Sara Wiskerchen said NAR’s Meetings & Conference Committee selects keynote speakers they deem among “the nation’s foremost thinkers, leaders or innovators,” such as Presidents Bill Clinton and George H.W. Bush, Secretary of State Condoleezza Rice, business executive Michael Eisner, television journalist Tom Brokaw, and many other celebrities.

Mark Kelly was selected because ... he exemplifies leadership, the importance of teamwork and courage under pressure."

“Mark Kelly was selected because he’s an American astronaut, a retired U.S. Navy captain, a best-selling author, a prostate cancer survivor and an experienced naval aviator who flew combat missions during the Gulf War,” she said.

“He exemplifies leadership, the importance of teamwork and courage under pressure, which is why NAR is very excited to have him and [the] former U.S. congresswoman accept our invitation to address this year’s attendees.”

NAR increased annual member dues by $40 in 2012 to raise money for political advocacy at the local, state and federal level and take advantage of a Supreme Court ruling removing limits on independent expenditures. NAR says it backs candidates who support the “Realtor Party” agenda, funding re-election campaigns of influential Democrats and Republicans alike.

Another celebrity in attendance at the group’s annual convention will be Jennifer Hudson, an Academy Award-winning actress, Grammy Award-winning recording artist and best-selling author. Hudson, who landed a star on the Hollywood Walk of Fame in November, will perform at the conference.

Registration for the event opens on May 7. The conference’s website, including a full conference schedule, will go live at around 1 p.m. Eastern today.
